Actually..if your smart, you can write a program to spin the disk at a certain RPM in c++ and then that certain rpm emits a radio transmission that can be picked up by another computer and have that data written to its hard drive (encoded and encrypted of course) completely pointless unless your wanting to steal information of a computer that your not allowed to bring anything such as writeable disks..flash drives, SD cards, hard drives, pen drives... lol.....
